It’s a confident woman who can bake herself a giant chocolate chip cookie cake for her own birthday, bring it to a public place to share it, then publish it on the very public interwebs. Or at least that is what this now-31-year-old is telling herself.

Hi, I’m 31 today!

Every year of elementary school, I begged my mom to buy a double-frosted cookie cake from the Great American Cookie Company at the mall so I could bring it to class as my birthday treat. The kids who brought the Great American chocolate chip cookie cakes were the coolest.

In high school, I matured. Instead of buying my chocolate chip cookie cake, I learned to make “homemade” chocolate chip cookie cake with cake mix. I even demonstrated it for my cooking class (a home-ec type course appropriately titled “Foods”) for extra credit.

Now, we are entering Cookie Cake Phase III.

This is a recipe for real, homemade chocolate chip cookie from scratch, no cake mix or canned frosting to be found. It is hands down the best chocolate chip cookie cake I have ever eaten.

Imagine the best homemade chocolate chip cookie you’ve ever had. Now, make it 10 times bigger and easier to bake, because you don’t have to individually shape each cookie. Now you have the idea.

How Do you Make a Cookie Cake?

This Chocolate Chip Cookie Cake is melt-in-your-mouth soft at the center, lightly crispy at the edges, and beautifully buttery throughout. Making this giant cookie cake recipe will feel similar to making regular cookie dough.

  • To begin, whisk together the dry ingredients. Easy-peasy. A pinch of nutmeg is my secret ingredient to this cake’s special, extra-addictive flavor.
  • Next, beat together the butter and sugar. Be sure your butter is room temperature but not overly, puddly soft to give your cookie cake the best consistency.
  • Next, beat in the egg and egg YOLK. I added one extra yolk to give the cookie cake just the right amount of richness. Be sure you beat the egg and egg yolk in one at a time as directed. Your patience will be rewarded.
  • Now, chocolate chips. This cake has more chips than you’d dare call appropriate, and you’ll love every single bite.
  • Once your dough is ready, shape and chill it for your pan. I know it’s tempting to skip refrigeration, but it is necessary for the recipe.
  • Bake. Frost. DEVOUR.

This cookie cake recipe took me a few tries to get right, but it was unbelievably worth it. which means that the week I made it, I had three enormous containers of chocolate chip cookie cake sitting on my kitchen counter, each with a slightly different tweak to the recipe.

In an adult-version of bringing birthday treats to class, I carted all three containers to dinner with my girlfriends. We debated the merits of each recipe, and declared today’s version the winner!

This cookie cake marks my FIFTH year of sharing a cake on my own birthday. While admittedly self-indulgent, I also enjoy seeing the progression from year to year, both in terms of the recipe photography and of my own attitude. On my 30th birthday when I made this Lemon Layer Cake, I wrote openly about how funky hitting the milestone 3-0 made me feel.

Now, 365 days later, reading that post makes me giggle a little bit because, if anything, I’ve felt like 31 for the past three months. I even filled out a form where I accidentally listed my age as 31! Does this mean I’ve entered the life phase where I have to pause and carefully think about what age I am to get it right? Maybe.

I can tell you that I have definitely not hit the age where I’m too old to bake myself a giant chocolate chip cookie birthday cake, and I hope I never do.

I can’t predict what 31 has in store for me, but if my current blessings—fulfilling relationships, a career I love, my health, and so many more—are any indication, this might be my best year yet.

To-die-for easy homemade cookie cake with chocolate chips. This rich, chewy, giant cookie cake recipe is perfect for birthdays and special celebrations!


For the Chocolate Chip Cookie Cake:

  • 1 cup all-purpose flour
  • 1 cup white whole wheat flour or whole wheat pastry flour
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon freshly grated nutmeg — optional
  • 10 tablespoons unsalted butter — softened to room temperature
  • 2/3 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1 teaspoon kosher salt
  • 1 large egg — plus 1 egg yolk, at room temperature
  • 1 tablespoon whole milk*
  • 2 teaspoons pure vanilla extract
  • 1 1/4 cups semisweet chocolate chips

Chocolate Fudge Frosting (optional):

  • 1 1/2 cups powdered sugar — plus 2 tablespoons
  • 1/4 cup unsweetened cocoa powder
  • 6 tablespoons unsalted butter — softened to room temperature
  • 2 tablespoons whole milk*
  • 1/2 teaspoon instant espresso powder — optional—it will intensify the chocolate flavor without making the frosting taste like coffee
  • 1 teaspoon pure vanilla extract
  • Pinch kosher salt — to taste


  1. For the Chocolate Chip Cookie Cake: In a medium mixing bowl, whisk together the all-purpose flour, whole wheat flour, baking soda, and nutmeg.
  2. In the bowl of a standing mixer fitted with the paddle attachment or a large mixing bowl with a hand mixer, beat together the butter, brown sugar, granulated sugar, and the salt on medium speed until smooth, about 3 minutes. Add the whole egg, beating for 1 minute and stopping to scrape down the bowl before adding the egg yolk. Beat for another minute and scrape down the bowl again. Beat in the milk and vanilla.
  3. Reduce the mixer speed to low, then slowly add the dry ingredients, mixing just until the dough comes together and the flour has disappeared. Add the chocolate chips on low speed, finishing with a few stirs by hand as needed. Lay two large sheets of plastic wrap down on counter so that the long sides overlap slightly and you have one large, wide sheet. Scrape the dough into the center, then spread it into a thick disk. Fold the edges of the plastic up and around the dough to wrap it completely. Refrigerate for at least 1 hour or up to 3 days.
  4. When ready to bake, preheat the oven to 350 degrees F (if using a clear glass dish, reduce temperature to 325 degrees F). Generously coat a 9-inch springform pan, 9-inch pie dish, or 9-inch cake pan with baking spray. Press the dough into the pan in an even layer. Bake for 20 to 25 minutes, until the top is lightly golden brown and a toothpick inserted in the center comes out clean. Check at the 15-minute mark—if the cookie cake is browning too quickly at the edges, loosely tent it with foil. Remove from the oven and place the pan on a wire rack to cool completely.
  5. Meanwhile, make the Chocolate Fudge Frosting (optional): Sift the powdered sugar and cocoa powder together into a bowl. In a separate bowl, beat the butter on medium speed until light, smooth, and creamy, about 2 minutes. Reduce the mixer speed to low, then add half of the powdered sugar and cocoa mixture. Add all of the milk, espresso powder, and vanilla. Beat to combine, then add the rest of the dry ingredients and beat for 2 minutes until well combined. Taste and add a pinch of salt if the frosting seems too sweet.
  6. Frost and serve: Once the cookie cake has cooled, run a sharp knife around the edges to loosen it, then transfer it to a serving dish (you can also serve it directly from the pan). If desired, decorate with the chocolate frosting.

Recipe Notes

  • *You can use any milk for the frosting and cookie you like. I prefer something with some fat in it (such as whole milk, cream, or half and half) because it’s a small amount and results in a richer, creamier frosting.
  • Store leftovers at room temperature for up to 3 days.
  • Unbaked dough can be refrigerated for up to 3 days or frozen for up to 3 months.
  • Baked cookie cake can be frozen frosted or unfrosted for up to 2 months.
  • You may have some frosting leftover, which you can save for another use. Try it dipped with pretzels or spread over graham or Ritz crackers.
